I Will Be a Villainess & Survive

I gasped, sitting up from the center of my bed drenched in sweat. I held up a shaking hand towards my chest where a sword had been protruding previously.
'I'm not dead?' My mind was filled with confusion, as I slowly got out of bed to the standing mirror near my wall. My eyes widened as I glanced at the younger version of myself. It was me, but... This is definitely the same outfit I wore the night before getting officially engaged at the engagement party being held the next day. My mind processed everything quickly and I just had a feeling that what I just figured out was true. Somehow I had gone back in time to the day before my engagement. Before I got married to the jerk. Before my life became a misery. Before I was stabbed by my stepsister and killed while my husband stood by her side doing nothing. I closed my eyes.
I remembered everything. All the torture and things I had to go through at the hands of my husband, stepsister, and many others. I opened my eyes, and they quickly caught on to something hanging on my wall. It was the sword I had put away to become "feminine" and giving up what I love so I could become a better wife for my husband. I slowly smile and walk up to my precious sword on the wall.
"I won't fall for their tricks again, not this time." An evil grin starts taking up my face as I start to think of all the things I am ready to do to pay back those who owe me.
"This time they'll get theirs and won't know what hit them." I laugh, and stop.
"And if I find a man this time, it will be someone I won't change myself for."
